Setting circles are used to tell where the telescope is pointed in the sky. Use setting circles by reading ascension and declination with help from an astrophotographer in this free video on astronomy and telescopes.

  • is that a toy?

    

  • Great video, finally I understand hoy to use the setting circles of my equatorial mount. I thought something was wrong with my mount because the RA circle was always pointing strange coordinates, until I saw that you can/must adjust it every session of observation by aligning it with a known object. Muchas Gracias! 

  • it is huge  and so is he

  • I have a question, how would you locate 0h right ascension from your location? Say you were dropped in the middle of nowhere and had to navigate your way using the CCS, how would you know where 0h RA is at? Would a compass help?

  • I'm sorry I'm not listening to you... i am more disturbed and looking at the telescope behind. Why not make another video and just showcase that huge thing, :o)

  • Wow, that telescope is a huge thing....

  • Wow, that telescope is a huge thing....

  • Great job!

    Finally starting to get my head around this.

    Thanks!

  • Really helped me get a better idea of Sidereal Time and how to measure it. Thank you.

  • The cutest astronomer I've ever seen!
